i have redline 75w-90 in my Manual Transmission Differential gearbox but i want to switch it out because last time i check and did a little bit of drain all i saw was it was kind of watery so i just add more in. I have pentosin 75w-80 in my manual transmission, my local town doesn't carried pentosin 75w-90 so i have to special order it online if i want it. I don't want to put redline again into my differential gearbox, my local town carried redline, motul, mobile 1 and many other brand, so have anyone try "Motul" gear oil before? should i order pentosin 75w90 or try motul, here the link to motul gear oil

[QUOTE=lcoleman;14877059]There is certainly nothing wrong with Motul, aside from the astronomical price. What is your aversion to Redline, out of curiousity?

i put redline 75w-90 in and drove for about 3k miles, i drain the plug and the oil came out kind of gray and maybe kind of watery, i didn't bother to touch or feel it, when i put redline in my differential i think the oil color was yellow to orange, sometime it hard shifting to 1st, 2nd and 5th when changing gear sometime when the car is cold, so i just want to try something new to c if it help the problem, no dislike on redline or anything just wants to try other brand
